Helminth parasitism in the Neotropical cormorant, Phalacrocorax brasilianus, in Southern Brazil: effect of host size, weight, sex, and maturity state

Parasitology Research, 2011
Forty-seven specimens of Neotropical cormorants, Phalacrocorax brasilianus, from Lago Guaíba, Guaíba, State of Rio Grande do Sul, Brazil (30° 00' S, 51°15' W), were examined for helminth parasites between 1999 and 2003. Twenty species of helminth parasites were found: ten digeneans: Austrodiplostomum mordax, Austrodiplostomum compactum, Clinostomum sp.,

Cardiovascular physiology of embryonic neotropic cormorants (Phalacrocorax brasilianus)

Comparative Biochemistry and Physiology Part A: Molecular & Integrative Physiology
Cardiovascular maturation in avian species has primarily been studied in precocial species of birds, with few studies conducted on altricial species, which make up the majority of avian species. In the precocial species of birds studied to date, cardiovascular regulation is derived primarily from an adrenergic receptor stimulation that is present from ...

Parasite communities of the neotropical cormorant Phalacrocorax brasilianus (Gmelin) (Aves, Phalacrocoracidae) from two coastal lagoons in Guerrero state, Mexico

Parasitology Research, 2011
The parasite community structure of the neotropical cormorant, Phalacrocorax brasilianus, from two lagoons (Coyuca and Tres Palos) from Guerrero state, México, was examined. Fourteen species of adult helminths (6,391 individuals) from 48 cormorants were identified: 9 digeneans, 1 acanthocephalan, 1 cestode, and 3 nematodes.

Ecological functions and economic value of the Neotropic Cormorant (Phalacrocorax brasilianus) in Los Olivitos Estuary, Venezuela

Environment and Development Economics, 2011
ABSTRACTWe present the ecological functions of cormorants and estimate the economic value of these functions to artisanal fishermen, as a valuation exercise for Neotropic Cormorants at Los Olivitos Estuary, Lake Maracaibo, Venezuela. Ecological functions were based on estimating the abundance, distribution and diet of cormorants; economic values were ...

Primer reporte de Coccidiosis renal fatal en un Biguá (Phalacrocorax brasilianus) en coinfección con nematodes de Argentina

2022
شهدت عينة من البيغوا (Phalacrocorax brasilianus) التي تخضع لظروف الإدارة السريرية، بعد إنقاذها في حالة ضعف، تحسنًا عامًا ملحوظًا ثم عانت من تغيير مفاجئ نحو تطور غير مواتٍ حتى النتيجة المميتة في غضون بضع ساعات بسبب الفشل الكلوي الحاد. أظهر تحليل نتائج الدراسات السريرية والنتائج المرضية النسيجية بعد الوفاة وجود عبء كبير من الديدان الخيطية المعوية ...
